Comparative transcriptomicsof fungi Group Nicotiana Daan van Vliet, Dou Hu, Joost de Jong, Krista Kokki
Research objective To study differences in gene expression in related fungi species Studies species: Reference genome RNA reads > 100 bp Preferably: Paired-end Related species (or at least: single-celled, eukaryotic) Similar conditions
Data Management • Cleaning and trimming reads: FastQC(<25) Under Pipeline: • Mapping reads: TopHat • Assemble and quantify transcripts: Cufflinks • Final transcriptome assembly: Cuffmerge • Extracting the transcripts: gffread
Data Management Correlation between expressed gene and transcript properties • determine GC content and transcript length • determine intron length • codon usage (loop analysis codon by codon; count frequencies of codons in array ) Validation • Run scripts on small, example datasets automating in the pipeline
Data Processing Module building • Organize the components of our project • Separate project in functional blocks Visualization and Interaction network • Compare different dataset or same species in different conditions -- Cuffdiff • R and Cytoscape to make visualization in interaction network
